Abstract: An integrated transmission apparatus includes a plurality of optical supervisory channel (OSC) processing units for processing OSC signals contained in a wavelength division multiplexing (WDM) signal received from a WDM network and a switching unit for performing the path control of synchronous digital hierarchy (SDH) frames. An OSC processing unit transmits the SDH frame, containing wavelength information indicated by, to the switching unit. Another OSC processing unit acquires the SDH frame, containing wavelength information, from the switching unit and sets an OSC signal which is to be appended to the WDM signal to be transmitted, based on the wavelength information.

Abstract: The step support (17) or plate support comprises a rear crossmember (22) and a front crossmember (24) which together form a plane (E3) for receiving the tread element (9). There are two outer step cheeks (20.1, 20.2), wherein one of the step cheeks (20.1) is arranged on the right and one of the step cheeks (20.2) is arranged on the left, substantially perpendicular with respect to the crossmembers (22, 24). The two crossmembers (22, 24) are manufactured from deep-drawing sheet metal and are welded or joined or riveted or screwed or adhesively bonded or clinched to the step cheeks (20.1, 20.2) or plate cheeks to form a load-hearing frame. The height (H2) of the crossmembers (22, 24) at its ends is smaller than the height (H3) of the crossmembers (22, 24) in the center, with the result that the crossmembers (22, 24) have a curved shape.

Abstract: An equalizer circuit receives digital amplitude data A[N] which represents the amplitude level of the N-th (N is a nonnegative integer) signal to be transmitted via a transmission line and timing data T[N] which represents the cycle of the signal, and performs waveform shaping. The equalizer circuit includes: M (M is an integer) calculation units ECU1 through ECUm; and an adder ADD1 which adds the output data of the M calculation units ECU1 through ECUM and the amplitude data A[N] together so as to generate equalized amplitude data D[N]. A step response waveform RSTEP(t) for the transmission line is approximated by Expression RSTEP(t)=SSTEP(t)·(1?Sj=1:M fj(t)) using M (M is an integer of 2 or more) functions fj(t) (1?j?M) and a step waveform SSTEP(t) with the time t as an argument. The representative value of the function fj(t) in a range between T1 and T2 is represented by a function gj(T1, T2).
Abstract: A quadrature amplitude modulator is provided. An oscillator generates an in-phase carrier signal having a rectangular wave, a trapezoidal wave or a waveform similar to these, and a quadrature carrier signal, the phase of which is shifted by ¼ cycle relative to the in-phase carrier signal. A multi-level driver generates an in-phase modulated signal by amplitude modulating the in-phase carrier signal with an analog in-phase baseband signal having a discrete voltage level or current level in accordance with the in-phase baseband data. Likewise, the multi-level driver generates a quadrature modulated signal by amplitude modulating the quadrature carrier signal with an analog quadrature baseband signal having a discrete voltage level or current level in accordance with the quadrature baseband data The multi-level driver generates a modulated signal, the amplitude of which takes a discrete level, by combining the modulated signals together.
Abstract: A well tubing valve including a substantially tubular body connected in a tubular string and a rotational valve member having at least one aperture. The valve member is a sleeve having a part spherical surface, is rotationally moveable relative to the body to align and misalign the at least one aperture in the valve member with a port in the body. The valve member is actuable to rotate relative to the body in a single direction, and moves from the open position to a closed position and back by rotation in the same sense. The valve also includes a sealing arrangement adapted to provide a metal seal that is biased to seal against the part spherical surface.
